Angiographic morphology suggestive of plaque rupture such as type II irregular lesions has been identified in the majority of stenoses associated with
Mar 22 2017 Femoropopliteal artery disease accounts for a significant proportion of endovascular interventions EVTs for peripheral artery disease PAD in patients with disabling claudication or chronic limb ischemia. The femoropopliteal artery starts from the common femoral artery CFA to the superficial femoral artery SFA and ends at the popliteal artery. The SFA

was then defined as 100 occlusion rate residual neck filling Roy class2 as95 occlusionrate andresidualaneurysmfilling Royclass 3 as a less than 90 occlusion rate. Quantitative Computerized Angiographic Evaluations On calibrated images of the respective DSAs 1 to 2 projections were selected for evaluation.
May 01 2015 The current analysis of 32 cases of angiographic occlusion for recently bleeding or actively bleeding duodenal varices reveals an 87.5 rate of successful hemostasis and a 3 rate of major complications. This high success rate is clinically useful given the 40 short term mortality of untreated bleeding duodenal varices.
Therefore the appropriate treatment option can be determined on the basis of CT angiographic findings. The prototype workstation which was established at our institution by an interdisciplinary working group of radiologists technicians and computer scientists allows use of peripheral CT angiography in daily routine.
Inter observer agreement was excellent for both the assessment of aneurysm occlusion k=0.89 C.I.=0.81 0.99 and parent artery patency k=0.90 C.I.=0.76 1.0 . CONCLUSION The proposed schema is sufficiently sensitive to register gradual aneurysm occlusion and parent artery patency on interval angiograms.

1 day ago In the 19 included studies there were 580 patients with 604 aneurysms of which 6.1 were acutely ruptured and 28.3 were previously treated. Procedural complication rate and symptomatic stroke occurred in 9.8 and 7.5 of patients. Complete occlusion rate at last radiographic follow up mean 12.1 months was 73.6 .
Mar 26 2016 Variability in the angiographic assessment of vessel diameter and other measurements can be introduced by a number of factors including biologic differences among lumen diameters e.g. reference vessel size vasomotor tone thrombus and inconsistencies in radiographic image acquisition parameters e.g. quantum mottling out of plane
c Class IV ISR with total occlusion. Lesions have a TIMI flow grade of 0. Angiographic Analysis An independent core angiographic laboratory performed qualitative and quantitative angiographic analyses. All cineangiograms were analyzed using a computer assisted automated edge detection algo rithm ARTREK Quantitative Cardiac Systems .
This was supported by angiographic data in which the collapse group CTO was longest compared with the other two groups Table 3 however comparison of occlusion length measured by QCA and CCTA and IVUS in the 75 lesions that had IVUS imaging using automatic transducer pullback showed that the collapse group IVUS occlusion length was

Tables 1 and 2 summarize the clinical and angiographic characteristics of the 249 patients with occlusions compared with the 2701 with stenoses. Patients with total occlusions were younger and had a significantly higher rate of previous

Inter observer agreement was excellent for both the assessment of aneurysm occlusion k=0.89 C.I.=0.81 0.99 and parent artery patency k=0.90 C.I.=0.76 1.0 . Conclusion The proposed schema is sufficiently sensitive to register gradual aneurysm occlusion and parent artery patency on interval angiograms. It is reproducible and is applicable
Objective The purpose of this study was to prospectively investigate the correlation between CT angiographic clot load CTACL score pulmonary perfusion defect PPD score and the global right ventricular function in the assessment of pulmonary embolism PE severity. Methods 49 patients with acute PE who underwent dual source CT scan were included in the study.
Mar 18 2017 The balloon is inflated with angiographic confirmation of complete occlusion of the vessel in question. The balloon is inflated for a total duration of 30 minutes and a neurologic examination is performed by the operator every 5 minutes Fig. 1 .
Occlusion of the catheters occurred in 44 of the cases and the average time to obtain occlusion was 8.5 min 3 15 min . Values of the decrease rate of BFR in ml/min2 allowed separation of the catheters into 3 groups of low medium and high thrombogenicity. However occlusion occurred at least one time for each type of catheter.

Sep 01 2012 BACKGROUND AND PURPOSE The initial angiographic occlusion rate is the strongest predictor of later rebleeding in previously ruptured coil embolized cerebral aneurysms. Angiographic estimations of aneurysmal occlusion rates are however subjective in nature and confounded by methodologic problems. COR has been developed and its superiority has
